(Solved) - LIghthouse , light simulation.

Hello, Father of my freind bild the lighthouse that he wasa rased with is mam and a sister.
He make it to the scale of 1/12'' , it is the perfect picture reproduction, but this man is 80 years old,
and still going, but one thing does dot go has plan,,,, - the light it self- ,,, he tryed avrey thing, and doesn't get the effec desire,
so I got the idea of doing so for him , an it is,,, and here is werte you peoples could give me a hand.
I'm tinking of using a car light bulb- headlight- those whow are almost blue, and with a little ship set and processor and a board, make a little serquet ??? that would control the ligth ex' light on for 2sec, off1sec, on 1sec, and start over again,,
I'm sory about my writhing I hope you get an idee of what im looking for,, of corse, I would bild that here following your instruction,, thanks
Richard
